SyncToy from Microsoft
Graeme sent me this link for a free tool from Microsoft called SyncToy v1.4 (Also in 2.0 beta version, but have not tried that) that allows you to copy, move and synchronize different directories on your computer. This is ideal if you want to make sure you copying backups of your digital photos as I know with more and more people using these types of camera’s it’s very easy to lose you photographic work, indeed I think I currently keep around 3 back ups in different places of the photographs I take and even then I am sure I have lost a few, so this tool should be incredibly helpful in taking the manual labour of oh keeping backups.
